The effects of glucose-fructose co-ingestion on repeated performance during a day of intensified rugby union training in professional academy players

Figures & data

Figure 1. Schematic of trial days. GPS = global positioning system, sRPE = session RPE

Figure 2. Mean speed (a, b), mean heart rate (HR) (c, d) and rate of accelerations (e, f) during two sessions of small-sided games separated by a 3-h recovery period, during which carbohydrate-protein drinks containing either glucose-based carbohydrates (GLUCOSE ONLY) or glucose-fructose mixtures (GLUCOSE+FRUCTOSE) were ingested. HR_max, maximum heart rate. Data are means ± 95%CI. n = 9 rugby players

Figure 3. Overall RPE (a), leg muscle exertion (b), fatigue (c) and breathlessness (d) ratings after two sessions of small-sided games separated by a 3-h recovery period, during which carbohydrate-protein drinks containing either glucose-based carbohydrates (GLUCOSE ONLY) or glucose-fructose mixtures (GLUCOSE+FRUCTOSE) were ingested. Data are means ± 95%CI. n = 9 rugby

Figure 4. Blood lactate concentration (a), a composite gut rating (b), and the constituent gut rating scales (c-h) during recovery from a session of small-sided games, with ingestion of carbohydrate-protein drinks containing either glucose-based carbohydrates (GLUCOSE ONLY) or glucose-fructose mixtures (GLUCOSE+FRUCTOSE). Data are means ± 95%CI. n = 9 rugby players
